Today, let's discuss the four main characteristics of garbage companies that smart people never want to stay in, while fools are happy to do so. 

First, the recruitment process lacks structure. Companies that recruit people every day but can't retain them often have issues that make employees unhappy, such as poor policies, inadequate compensation, or lack of promotion opportunities. Without a sense of hope, future prospects, or direction, employees will leave.

Second, compensation is not well-structured. Many small startup companies lack standardized salary criteria and mainly depend on the whims or subjective judgments of leaders or bosses. If they like you, they may give you more, but if they don't, they may reduce your salary. Without an effective hierarchical system, salary increases become a matter of luck.

In contrast, big companies have clear rules stating that only employees who meet certain requirements can get a raise. This fosters fair competition and encourages employees to work harder for money. 

Third, work is not quantified or allocated properly. Many garbage companies have unreasonable work distribution and planning.

Some employees are overloaded, working long hours and unable to complete their tasks, while others have an easy workload and contribute little value to the company, yet they receive the same salary. It means there is no difference between doing a good job or not, and employees lose motivation. Instead of working hard, many prefer slacking off and enjoying their days with a fixed salary. 

Fourth, there is no clear assessment criteria. Employees only focus on what the company assesses instead of doing what their leaders expect. The lack of assessment criteria makes it difficult to provide clear direction and standards, and employees' behavior cannot be effectively regulated. Without solving these issues, execution becomes challenging, and plans cannot be implemented effectively, which ultimately leads to the company's decline.

These four characteristics are what garbage companies possess. So when choosing a company, it is crucial to discern these traits and not be casual in your decision. Otherwise, you will waste your youth without gaining anything.
